摘要 比较了不同化学刻蚀时间后铝箔集流体的表观形貌和比表面积,用交流阻抗、恒流充放电和循环伏安等测试分析了铝箔制备的电极的性能。随着铝箔刻蚀时间的延长与腐蚀程度的增加,电极的比电容增大、等效串联电阻减小;当刻蚀时间为80 s时,电极的比电容(165.2 F/g)最大、等效串联电阻(1.4Ω)最小;刻蚀铝箔集流体制备的电极以0.3 A/g的电流在0~2.7 V循环2000次,电容衰减率不超过1.1%。 The apparent morphology and specific surface area of aluminum foil collector after chemical etched for different time were compared;the performance of electrodes prepared by aluminum foil was analyzed by A.C. impedance,galvanostatic charge-dis-charge and cyclic voltammetry. With the etching time prolonged and corrosion degree increased,the specific capacitance of the elec-trode increased,the equivalent series resistance decreased. The biggest specific capacitance of 165.2 F/g and smallest equivalent series resistance of 1.4Ωof electrode could be obtained when the etching time was 80 s. When cycled for 2 000 times with the cur-rent of 0.3 A/g in 0~2.7 V,the capacitance decay rate of electrode prepared by etched aluminum foil was less than 1.1%.
